Product Description

Product Overview

The Raspberry Pi RP2040 mini is a microcontroller developed by Raspberry Pi. It's the first microcontroller designed in-house by Raspberry Pi, featuring a dual-core ARM Cortex-M0+ processor running at 133MHz, 264kB of SRAM, and support for up to 16MB of off-chip Flash memory via a dedicated QSPI bus

Key features

• Dual ARM Cortex-M0+ Processors: Running at 133MHz, these provide a good balance of performance and efficiency.
• 264kB On-Chip SRAM: This is divided into six independent banks, providing ample memory for most applications.
• External Memory Support: The RP2040 supports up to 16MB of off-chip Flash memory via a dedicated QSPI bus.
• DMA Controller: Facilitates faster data transfers without loading the CPU.
• AHB Crossbar: Allows multiple masters to access peripherals simultaneously without conflict.
• Programmable LDO: The on-chip LDO can generate core voltage, which can be adjusted for different power requirements.

Specifications

1. Dual ARM Cortex-M0+ CPUs: Operating at 133MHz, these provide the processing power for the microcontroller.
